1N4004G-K

Single Diodes Overview

The 1N4004G-K is a silicon rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a glass passivated chip junction and is housed in a DO-204AL (DO-41) axial leaded package. The device is designed for general-purpose rectification applications requiring high reliability and low forward voltage drop. Key electrical characteristics include a maximum repetitive peak reverse voltage of 400V and an average forward rectified current of 1.0A at 25°C ambient temperature. The component complies with RoHS directives and is halogen-free, ensuring environmental safety standards are met while maintaining robust performance under standard operating conditions.

Single Diodes Feature Summary

• Glass passivated chip junction construction for enhanced stability
• High surge current capability to handle transient overload events
• Low forward voltage drop for improved power efficiency
• Halogen-free material composition compliant with international standards

Single Diodes Applications

• General-purpose rectification in AC/DC power supplies
• Reverse polarity protection circuits
• Freewheeling diodes in inductive load switching
• Buck converters and DC-DC step-down modules

Single Diodes Procurement Notes

Verify the specific suffix 'K' against official Taiwan Semiconductor documentation to confirm if it denotes a distinct packaging variant or quality tier compared to the standard 1N4004G. Ensure that the procurement source provides valid datasheets confirming the exact electrical parameters and mechanical dimensions match the required design specifications before finalizing orders.

Single Diodes Selection Notes

Select this component when a standard 1A silicon rectifier with 400V blocking capability is required in an axial through-hole package. Consider the glass passivation for superior junction stability compared to epoxy-passivated alternatives. Evaluate thermal management requirements based on the DO-41 package's heat dissipation limits during continuous operation in enclosed environments.

Single Diodes Part Context

This part belongs to the widely used 1N400x series of general-purpose silicon rectifiers. The 'G' suffix typically indicates glass passivation and halogen-free compliance within the manufacturer's lineup. The 1N4004 variant specifically targets 400V reverse voltage applications, bridging the gap between lower voltage 1N4001/0002 parts and higher voltage 1N4005/0006/0007 variants.

Single Diodes Replacement Considerations

Direct replacements include other manufacturers' 1N4004 diodes with identical DO-41 packages and electrical ratings. Verify pinout compatibility and ensure substitute components meet the same RoHS and halogen-free requirements if environmental compliance is critical for the end application.
